Big problem with the set bonus

Poehalkukuhoi

Received a fiery staff of "mother's sorrow" of blue quality, sharpened to yellow. Going to the guild store, find out the prices for things, but noticed that I had less characteristics than the item in the store (I compared it in other stores, I also asked the guilds). The characteristics are underestimated only for me.

You have Mother's Sorrow set equipped on your character, are all parts of it golden quality? If some parts of it are purple, this is normal to see less stats when comparing items - because compared item shows you stats for all 5 golden pieces.
